“On March 23, 2011, USEC signed a new multi-year contract with TENEX for the 10-year supply of Russian LEU beginning in 2013. Under the terms of the new contract, the supply of LEU to USEC will begin in 2013 and increase until it reaches a level in 2015 that includes a quantity of SWU equal to approximately one-half the level currently supplied by TENEX to USEC under the Megatons to Megawatts program. The contract provides USEC the option to increase or decrease the amount of the firm commitment SWU to be purchased for a given year by up to a total of plus or minus 5%. For years 2015 through 2019, in addition to its option to decrease the amount of any firm commitment SWU to be purchased during such year by up to 5%, USEC will have the option to defer up to an additional 5% of the amount of the firm commitment SWU to be purchased in such year and instead purchase the deferred amount in years 2020 through 2022. TENEX and USEC also may mutually agree to increase the purchases and sales of SWU by certain additional optional quantities of SWU up to an amount beginning in 2015 equal to the amount USEC now purchases each year under the Megatons to Megawatts program. Unlike the Megatons to Megawatts program, the quantities supplied under the new contract will come from Russia’s commercial enrichment activities rather than from downblending of excess Russian weapons material. As this new agreement is separate from the Megatons to Megawatts program, remedies provided to DOE under the 2002 DOE-USEC Agreement related to USEC’s role under the Megatons to Megawatts program do not apply to the new purchase agreement. However, the LEU we obtain from TENEX under the new agreement will be subject to quotas and other restrictions applicable to commercial Russian LEU that do not apply to LEU supplied to USEC under the Megatons to Megawatts program.”
That 2022 date has now been extended, through 2023 (via the NRC license and amendments).
